Electrochemical performances of Li-air batteries.
(a) The first charge/discharge curve of Li-air batteries using XC-72 carbon, LaNiO3 and 10 wt.% CNL as the air electrode at a current density of 50 mA g−1. (b–d) Discharge and charge curve of the cells at a current density of 250 mA g−1 using 10 wt.% CNL, LaNiO3 and XC-72 carbon as the air electrode, respectively.
